Severe noise in reconstruction results

Hi, i really appreciate your work! When i reconstruct my face, i found there is severe noise above my head，also my facial patches are not smooth. May I ask what the reason is？ 2023-09-08 14-24-35 的屏幕截图

Hi @xuduo18311199384

Great results!

The noise of reconstruction generally comes from the homogenously color-ed background (eg., pure white) or unobserved regions. If you consider these undesirable, you can filter out these regions by keeping the maximum connected mesh, given that you know there is only one object that you want to keep. Trimesh offers great tools to compute such information here. I hope this helps!

Hi @xuduo18311199384 Can you provide tips on how you recorded this video? Did you do any pre-processing, or did you solely use COLMAP for the poses? Additionally, could you share your setup in terms of GPU, memory, etc.?

I'm trying to do something similar, but I'm facing issues.

Best regards, Lucas.
